SL_E_SFS_INVALID_TOKEN_DATA_HASH
Where the failure occurs in Software Protection Platform
Keep the symbolic result SL_E_SFS_INVALID_TOKEN_DATA_HASH together with HRESULT 0x8004E108. The producer is the serialized Token Store file format; at the low-level reader/writer that validates the Token Store container, descriptor table, token records and transaction state before licenses can be evaluated, Windows determined that the protected token payload no longer matches its recorded integrity hash.
This distinction matters because this is payload-integrity failure, unlike a descriptor or record-length inconsistency. A later “not licensed” state should not replace the first exact HRESULT in logs.
Where it sits in the licensing pipeline
A structural Token Store error occurs before an individual product key can be accepted or rejected. To verify this, retain token identifier, expected and computed hashes, file-system health results and the first event after the last successful evaluation.
The diagnostic record that matters
- file-system result and Software Protection event
- Tokens.dat or the applicable licensing-store file
- store header and format version
- descriptor table and token offsets
- token name, extension, declared size and hash
Why the symbolic code matters
| Result | Different condition |
|---|---|
SL_E_SFS_FILE_READ_ERROR | Compared with this result, the store reader could not obtain required bytes from the licensing-store file. |
SL_E_SFS_TOKEN_SIZE_MISMATCH | Compared with this result, the token’s declared length disagrees with the bytes available in its serialized extent. |
SL_E_SFS_DUPLICATE_TOKEN_NAME | Compared with this result, two descriptor entries resolve to the same token name where the store requires uniqueness. |
Testing the failing stage
- Identify the caller and operation instance that produced
0x8004E108. - Collect the code-specific evidence: retain token identifier, expected and computed hashes, file-system health results and the first event after the last successful evaluation.
Recovery while preserving licensing evidence
Repair the cause of corruption and reload licenses or rebuild Tokens.dat using Microsoft’s supported sequence.
Representative case: A disk or backup corruption changes bytes inside an otherwise well-framed token record.
Actions that usually destroy useful evidence
- Do not assume a product-key change can repair a malformed container.
- Do not edit or copy individual records inside the signed store.
Technical references
- Rebuild the Tokens.dat file — supported state, API or recovery information relevant to this HRESULT.
- Software Licensing provider — reference for evidence collection and post-repair verification.
- SoftwareLicensingService WMI class — technical contract for the subsystem producing it.
- Slmgr.vbs options — official platform context used to interpret it.
